To all, whom it may canoes-n;

Beit known that I, VVALLAOE L. NEWELL,

a citizen of the United States, andgresident of the city 01:" Seattle,county of King, State of -Washington, have invented certain new anduseful Improvements in Cargo Han. dling Devices, of. which ,thefollowingis a specification.

My invention relatestoa, machine or apparatus, for handling cargobetween vessels; and docks, and particularly .cargo of. the. sort whichislmown as. package freight,that.v

is articles which" are put up in packages, and wlnchare generally,handled upon trucks,

The object of myj invention is to produce.

a typeof apparatus which may. be used to hoist cargo out -1 of a vessel,and place it .upon the trucking floor of thawarehouse, and conversely totransfer such cargofrom the ware; house to the hold of a vessel.

My invention comprisesrthe various elements and icombinations thereof,which will be hereinafter described, andthen particur larly pointed .outin .tl1e claims.

In the accompanying drawings I have shown. my, invention in asimpletypev of construction, the same being illustrative of :theprinciples of; my invention, and the preferred manner of carrying out tle sarne. I

Figurelis, a side elevation ,otmy device,

showing it in its relationto both thewares justin-gthe same tocompensate for varying.

distances to the elevator.

Fig. 6 is,asectionshowingonetype of construction of the telescopic oradjustable elevator guideways.

Fig. 7 is a detail, showing the mannerof vertically adjusting the towerand the boom. In the drawings 9 representsa warehouse which is set backa suliicient distance from the edgeof the dock to provide space for thetower of my device, and .90 representsa vessel which is lyingalongsideof the dock.

The tower 1 is mounted-upon wheels lO, which travel upon rails carriedbythe dock, southatthe device as a whole may betrayersed'along the edgeof the dock.

A boom 2, preferably oftruss construction, ishinged to the towerfat 11,to swing secured by other means.

in a vertical plane. The swingingof the boommay be done. byany...suitable means. As. herein shown the boom is supported andcontrolled in. its, swinging movements means of hosting cableslQ, whichpassover pulleys .13, mounted respectively at the outer 611Cl10f,tl16boom, andat the upper end ot theltowerh This hoisting cableis controlledes from, the. power plant, which is located at lttinthe basenot-thetower. When not in. use, the, boom is intended ;to;.be swung 1111- ward.to such a position as not to obstruct themovement of a vessel alongsidethe dock.

Theboom ,2 has a trucking floor thereon, the Same being preferablyprovided with an adjustable, se'ctionqorv sections, which may be movedor adjusted soas to be out of the. wayofs-thei elevator guidewayswhenthe boomis'raised, and-also so astoacoommo-y. datethe position ofthe elevator. guideways lengthwise of the boo1n. Suclradjustment may beby the means'shown in Figs. 4 and l 5, in which 3 represents a sectionof the floon so which may be afixedsection, and 30 repre sents asectionwhich is. adjustable lengthwiseof the boom, and is supported at anelevation just above the section 3, whereby. it may be moved lengthwisethe boon as mayfg5 be desired. 7 V The adjustablesectioir 30 ispreferably provided withfan inclinededge 31,150, that; trucks, may passfrom one section to the other withoutmeeting too serious an obstruction..90 These adjustable, sections may be. made in number, whatever isrequired to meet. the] necessities of the particular. case. The adsjustability of thefloor sectionsmay also be The elevator guideways whichin general. are represented in Fig. lby the figurel, of an. extensibleor. collapsible construction as by being made telescopic in character,so that after beingplacedin positionover the hatchways, the telescopicparts thereofmay ,belowered .into. the hold of the vessel. Varione meansfor raising and lowering these sections may be employed. I havenotherein illustratedany definite means for doing this 10s assuitablemeans for doing this would be evident. The. telescopic characterof these guideways maybe securedzby. the type of constructionshown inFig. 6. In this constructionthe bars 40 and their connected parts, beingthe outermost ends of the series, areconnected together and form'theupper-- mostsection, which section may or may not fbe adjustablevertically uponthe boom. The t bars ll and their connected parts formthe next section, and the bar 42 at the center of the series, forms thelowermost section.

These may be, hoisted and lowered to remove the guideways from thehatchways, or to lowerthem therein. Anyother suitable type ofconstruction than that shown, may be used as'a substitute therefor. v

The elevator guideways are preferably mounted so that they may beadjusted lengthwise of the boom. This may be securedby various means. Asherein shown, I employ a car 5, which 1s mounted upon a trackway' '50carried by the boom, thus permitting a limited movement of the carlengthwise the boom. To prevent overably'carried upon the car 5 by meansof a hinge or pivot 53. In raising and lowering the boom,.the elevatorguideways may' thus be permitted to swing, whereby'they' will at alltimes maintain a vertical position. 'Such position is indicated by thebroken line'position shown in Fig. 1. The position of the helevatorguideways when lowered, is shown by full lines inFig. 1. In the samefigure by dotted lines at 43, is shown the positions of thevarioussections of the elevator guideways-raised, or telescopedtogether. The number of telescopic sections may be varied to suit theconditions. The various sections "of the elevator guideways arepreferably provided-with means whereby theymay be steadied from thehatchways' and vessel, as forinstanceby means of bars 45, which areadapted to engage the hatchway combings.

' i Mounted upon the elevator guideways are platform elevators,preferably two in number, counterbalanced so that one is going up whenthe other is going down. In F 1g. 3

one of these is shown at the top, and the 'other at the bottom, thesebeing connected by ropes 60 which pass over pulleys, carried at theupper end thereof. These cables preferably are conducted over suitablepulleys tot-he power plant 14 and thence back.

The control position from which the operator handles the elevators, ispreferably located at the outer end of the boom, as for instance at thepoint 20, as in this position he is able to'see down the hatchways, and

see all along the boom in the warehouse.

'I have herem'shown the tower as composed of a base section 15, and anupper or main section 16, the latter being the section to which the boomis secured, and which also" carries the power plant. These two sectlonsmay be made'vertically adjustable, whereby the boom may be adjusted toaccommodate to delivery floors at somewhat different elevations.

The manner of raising and lowermg the upper sect1on'16 ofv the tower,may vary.

, The means herein shown consists of threaded bars 17, which areconnected by means of horizontal shafts 18 and bevel gears 19, so thatall of them may be operated alike and simultaneously.

In operating my device the tower is moved along its trackway upon thedock to the point where it registers with the opening in the warehouse,through which the freight isto pass, and also into registry with thehatchway of the vessel. The boom 2 is then lowered until it is over thehatchway. If necessary the car 5 carrying the elevator guideways ismoved along the boom until the guideways are directly over the hatchway.The guideway sections are then lowered until the lowermost reaches thelowermost deck, from which it is desired to take, or to which it isdesired to deliver freight. The elevator controlling cables are thenadjusted in length to reach the desired decks.

T he device is then operated by placing the freight upon the elevatorsand hoisting or lowering the same, as may be necessary to remove thecargo from the vessel, or to place it inthe vessel.

The cargo is preferably handled by means of trucks, which may be loweredwithin the hold of the vessel when cargo is being moved from the vessel,then rolled upon the elevator platfornisand hoisted to the truckingfloor of the boom, at which point they are run off of the elevatorplatforms and transferred to the warehouse.

WVhen freight is to be placed from the warehouse into the vessel, theorder of procedure is reversech'the trucks being loaded in thewarehouse, run out upon the boom and aboard the platform of an elevator,loaded into the vessel, and then removed to the point in the hold wherethe freight is being stored.

When in use, the space between the floor of the boom and the floor ofthe warehouse is bridged by a short section of flooring, or suitablegang-way 21.
